Dear Mulyadi,

Thank you for your response. And apologies for being impolite.

On AnonHugePages, I do not allocate them, some application is doing that in
our cluster and I have no way to tell which application it is, unless I can
hook up monitoring tools one each compute nodes that keeps track of which
application is allocating huge pages. Not sure if I even know how to do
that. Any hints will be helpful.

-regards!!
Prem

Dear Mulyadi,

Sorry for sending direct email. I am at a deadlock pulling my hairs and
can't seem to figure out (
http://lists.kernelnewbies.org/pipermail/kernelnewbies/2015-September/015111.html)
how to reclaim the AnonHugePage allocations when only system services are
running on them. Reboot is an option but too many nodes and this happening
frequently i need to know an alternate way out.

Any help is greatly appreciated.
Regards,
Prem

Dear Prem

Sorry that I can not promptly answer any question these days.

My quick conclusion is that, since you said you alocate huge page above,
then I guess huge page has different reclaim policy, that's why it might
not be released when your application terminated. maybe you forgot to
explicitly release them?

All in all, I appreciate you ask my help, but next time please make sure
that person is inviting you for direct discussion first, so you won't be
considered as impolite.
